While this might not directly address concerns from lawmakers and advocacy groups as to what Google is doing with information on the back-end it certainly ensures users that vulnerabilities won't be left exposed when changing their sign-on credentials.

In February, Google faced a firestorm of protests and courtroom dramas aimed at delaying changes to its new privacy policies, which went live March 1. The furor has died down, but the overall privacy debate is in full swing.

Google responded by saying it will add a "Do Not Track" button to its Chrome browser by the end of the year. Google had previously resisted such a move.

Internet Explorer 9, Firefox and Safari all have the technology in their browsers, although there are varying critiques on how easy it is to activate the technology.

Google is already required to file reports with the FTC on how it's improving privacy for users. The requirement is part of a consent order the company signed with the FTC in October. The order is part of a settlement with the agency over privacy violations related to the roll out of Google Buzz in 2010.
